Respuesta :
perimeter = 2 l + 2w
here l = 15 and w = 4
perimeter = ( 2 × 15 ) + ( 2 × 4 ) = 30 + 8 = 38cm
Answer: 38 cm
Step-by-step explanation:
Given : The expression 2/ +2w is used to find the perimeter of a rectangle with length / and width w .
For length 15 cm and width 4 cm, the perimeter of a rectangle will be :-
Perimeter : [tex]2(15)+2(4)=30+8=38[/tex]
Hence, the perimeter of a rectangle with length 15 cm and width 4 cm is 38 cm.
